Question

Can someone please help me?

Verify each trigonometric equation by substituting identities to match the right hand side of the equation to the left hand side of the equation.

cot x sec4x = cot x + 2 tan x + tan3x

Answer 1

This is as far as ive
gotten\[\frac{ 1 }{ sinxcos^3x}\]

Answer 2

I dont understand how he got cos x on top

Answer 3

can someone help me

Answer 4

Which one are you working on?

Answer 5

For the third one:
1 + sec2x sin2x = sec2x

Remember:\[\sec(2x)=\frac{ 1 }{ \cos(2x) }\]Knowing this:\[\frac{ 1 }{ \cos(2x) }*\sin(2x)=\frac{ \sin(2x) }{ \cos(2x) }=\tan(2x)\]So we have now:\[1+\tan(2x)=\sec(2x)\]Which is a general identity.

Answer 6

\[sec^2x or sec(2x)\]

Answer 7

I actually need help with the first 1

Answer 8

For the fifth one:
- tan2x + sec2x = 1
Just move the tan2x over to the right side, then we'll get a general identity (Just like the one I posted above.)
\[1+\tan(2x)=\sec(2x)\]

Answer 9

again, \[sec^4x\]or sec(4x)?

Answer 10

i didnt notice i put all the problems up there

Answer 11

cot x sec4x = cot x + 2 tan x + tan3x

Answer 12

hey, you didn't know, how can others help? they are different, completely. pal. You must post the right problems, please.

Answer 13

Alright sorry
